DOORSILL AND W'EATI-IEE STRIP.

Application filed August 21, 1925. Serial No. 51,555.

T 0 all 'w/ zom it may come m:

Be it known that I, THOMAS E. 'WALKER, a citizen of the United States, residing at Detroit, in the county of ll ayne and State of li lichigan, have invented certain new and useful Improvements in Door-sills and Weather Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

T his invention relates to a door sill and weather strip, and has special reference to that class of casement doors which ordinarily open inward and are made of metal frames having kick plates movable relative to a sill saddle.

My invention aims to furnish a casement door with a'novel Weather strip embodying two sealing members, but adapted to exclude the elements with one sealing member forming a trough to exclude rough elements and the other sealing member to exclude iine elements. These sealing members are adapted to cooperate with saddle members in positively sealing the bottom part of a door rela- The saddle members cooperate in forming another trough and together with a weather bar cooperate to the extent of preventing any kind of matter from passing under the bottom of the door.

My invention further aims to provide a weather strip construction that is durable and highly eflicient for the purpose for which it is intended, and the construction will be hereinafter specifically described and then claimed.

Reference will now be had to the drawing wherein Figure 1 is a horizontal sectional view of the door, partly broken away to show the weather strip and saddle construction, and

Fig. 2 is a vertical cross sectional view of the door and saddle.

In the drawing, the reference numeral 1 denotes a sill floor or other base provided with a transverse groove 2, and in said groove and extending onto the sill 1 is a cement filler and retainer 3 for a polished cast bronze saddle 4;. To further anchor the saddle 4 relative to the sill 1, the lower face of the saddle has a longitudinal depending angle bar or anchor 5 which extends into the groove 2 and is retained therein by the cementitious material 3. On the upper face of the saddle are longitudinal parallel spaced apart outer and inner sill members or ribs 6 and 7 respectively cooperating with the saddle in forming a trough 8.

Swingable above the saddle 4t is a door fran'ie 9 that may have hick plates or may have glass panels extending to the bottom rail 10 of the floor. The bottom rail includes a depending flange 11 and an upstanding flange 12. Suitably mounted on the upstanding flange 12, preferably by screws 13, is an overhanging bronze curved weather bar 1 1 Which overhangs the saddle member 6 in spaced relation thereto and forms some what of a hood at the outer side of the door frame.

Secured to the depending flange 11 by screws 15, or other fastening means, is a retaining strip 16, and between this strip and the flange 11 is sandwiched a yieldable non-metallic weather strip 17 that may be made of rubber, durable felt, or any yieldable material. This weather strip is adapted to contact with the inner face of the saddle member 7 and the top of the saddle l, and form an air tight connection between the door frame and the saddle.

Attached to the upper face of the retaining strip 16 by rivets 18 or other fastening means is the edge 19 of a resilient metallic weather strip 20 that may be made of brass or a non-corroding material. This weather strip is disposed at an angle to the bottom rail 10 and has a substantially horizontal wiping portion 21 terminating in an angularly disposed lip 22. The substantially horizontal portion 21 of the weather strip is adapted to wipe and frictionally contact with the saddle member 6 so that the weather strip bridges the gap between the saddle member 6 and thebottom rail 10, thereby extending over and closing the trough 8 of the saddle.

The angularly disposed lip 22 extends in proximity to the weather bar 14 and cooperates with said bar in excluding some elements from entering the trough-like configuration of the resilient metallic weather strip.

As the door is swung open. the metallic weather strip is adapted to ride over the saddle member 7 and when contacting with said saddle member be slightly flexed. This is in order that when the door isclosed the resilient weather strip will be flexedand exert a pressure on the saddle member 6, so that the elements cannot pass between the saddle member 6 and the resilient weather strip. Should for any unforeseen reason elements enter the trough 8, it is practically impossible for the elements to pass yieldable weather strip 17, therefore the two weather s/trips cooperate in providing a positive seal between the bottom rail 10 and the saddle 4t. Again, the resilient metallic weather strip affords suflicient pressure on the saddle member 6 to hold the door in a closed position against accidental opening. lVith the trough 8 in the saddle i, it is practically impossible for foreign matter to pass over the saddle or interfere with the upper surfaces of the saddle members (5 and 7, because said surfaces are wiped by the resilient metallic weather strip each and every time the door is opened or closed.

lVith certain minor modifications my weather strip may be applicable to various types of doors, and for this reason I do not care to confine my invention to any structural details other than defined in the appended claims.

hat I claim is:-

1. The combination of a doorliaving a depending fiange, a retaining strip under said door and secured to the door flange, a resilient metallic weather strip attached to said retaining strip and adapted to engage a sill, a yieldable weather strip mounted between said retaining strip and the door flange and adapted to engage the sill, and a weather bar carried by said door and overhanging said resilient metallic weather strip.

2. The combination called for in claim 1, wherein said resilient metallic weather strip has a trough-like configuration and extends beyond the outer side of the door and in proximity to said weather bar.

3. The combination called for in claim 1 wherein said resilient metallic weather strip is attached to the upper edge of said retaining strip and said yieldable Weather strip depends therefrom.

4. The combination with a sill and a door, of a saddle mounted on said sill and providing inner and outer sill members, a resilient metallic weather strip carried by said door and frictionally engaging the outer sill member, a yieldable weather strip carried by said door and engaging the inner sill member, and a weather bar on said door overhanging said resilient metallic weather strip.

5. The combination with a sill and a door, of a saddle mounted on said sill and providing inner and outer sill members, a resilient metallic weather strip carried by said door and frictionally engaging the outer sill member, a yieldable weather strip carriedv by said door and engaging the inner sill member, and a bottom rail for said door angular in cross section and providing a depending flange with said weather strips an chored in the angle of said bottom rail and the yieldable weather strip extending below said depending flange.

6. The combination of spaced apart sill members, a swingablc door bottom rail, a resilient weather strip carried by said bottom rail and extending outwardly from under said bottom rail and adapted to be sprung in riding over one sill member to friction-ally engage the other when said door is swung to a closed position, and another weather strip carried by said bottom rail and brought into engagement with the other sill member when said door is closed.

In testimony whereof I aflix my signature.

THOMAS E. WALKER.
